Maybe 6 years ago or so, Lake Erie was getting low. The marina that I was at had a short ramp. Pretty nice but it didn't go all the way to the bottom. It suddenly dropped off. If your trailer wheels went over the edge, you'd need a crane to get it out. Water was getting low so I made the decision to pull the boat out of the water just in case the level dropped further. I always said that the level was so low I had to parachute into my boat [fixed dock].
This year will be interesting later in the season. We continue to be in a drought situation which mean less water entering the lakes and therefore lower levels. As we pilots says, "Maintain situational awareness." Pay attention and behave.
